310 GROTE & ROBINSON. 



On tlie American Butterflies referred to the Genus CHARIS by Doubleday. 

 By A. R. GROTE and C. T. ROBINSON. 



Doubleday and Hewitson, (Text p. 452,) retain the Genus Charis 

 Huhner Verzeicliniss, for a generic group of Erycinidae species belong- 

 ing to which have been described under the genus "Nymphidia" or 

 "Nymphidium" by Authors. 



In the Verzeicliniss, Hiibner's genus is erected for two of Cramer's 

 species unknown to us in nature. Without specimefns of the South 

 American Butterflies referred to Charis by Doubleday and Hewitson, 

 we follow these Authors in associating our two United States species 

 with those referred to Hiibner's genus, but one of which species was 

 then known to the English Entomologists. 



These species are C. caenius Douhl. & Hevnt. {Nymphidia pumila 

 Bois & Lee.) and C. borealis {Nt/mphidia horealis Gr. & R.). 



After giving the characters af the genus Charis, Doubleday & Hew- 

 itson remark : "The majority of the species are further distinguished 

 by the hirsute eyes, a character wanting^ however, in Ch. caenius and 

 two or three allied species. The last named species is remarkable for 

 being the only butterfly of the family found in the United States (1. c.)." 



For the group so characterized, and of which our C. caenius is typi- 

 cal, we propose the name Calephelis. Judging from figures, indeed, 

 we may conceive that Calephelis is entitled to be received as a distinct 

 genus for which the term may with propriety be used. The following 

 is a synonomy of our two species.

Our specimens were collected in Georgia by Mr. Jas. Ridings, and 

 agree well with Boisduval's description and the figures above cited.

 Our specimens were collected in New York State by Mr. Grote in 

 July. "While closely resembling C. caenius this species is distinguish-
